Django testing Using pytest and Hypothesis for test generation
What we will cover during this presentation Pytest ● Pytest-django plugin ● ● Using pytest parametrization to generate tests Adding hypothesis into the mix ●
What to expect Beginners welcome! - Since we are focusing on pytest and hypothesis, you can use this techniques for other frameworks or testing in general - We won’t be going too much in depth, but hopefully you will have enough knowledge to start using it in your projects
What will we do - Make a website for keeping track of unicorns - Add new unicorn and list added unicorns
Before testing - Know what are you building - Play around with low fidelity prototypes aka get paper and start drawing - Write an API specification - Sleep - Rewrite API specification
Our first end-point
Our Unicorn model
Couple of test to make sure unicorns are ok
Our simple view up to this point
Sending invalid requests structure Two tests for the price of one
Sending invalid request data types
Enter the Hypothesis - Rewriting above tests using hypothesis - Benefits of testing all sorts of crazy inputs (unicode chaos)
Type to test valid text inputs with hypothesis Hundred tests with one simple fixture
